Starbucks, which relies on Kraft to distribute its packaged coffee in places like grocery stores, also noted (somewhat ironically) that it does not intend to discuss any negotiations publicly.

"Starbucks intends to keep the discussions with Kraft private and will not be providing further details or comments at this time," read the statement.

That notice sparked a testy rebuke from Kraft, which dispatched a retort via PR Newswire later that evening calling the pact "perpetual" and suggesting that it would cost Starbucks financially to nix the agreeemnt. Kraft also added that it won't discuss the matter publicly, while doing exactly that.

"Kraft Foods intends to keep the discussions with Starbucks private and will not be providing further details or comments at this time," read the statement from Kraft.
